(PDF) Manufacturing of Al2O3/Ni/Ti Composites Enhanced

Jun 24, 2021 · The NiTi phase diagram describes three stable intermetallic phases:NiTi, Ni3T i, and NiTi2, characterized by high hardness, wear r esistance, and good mechanical properties at Correlation Between Unsteady-State Solidification and Mar 02, 2021 · Commonly, intermetallic compounds (IMCs) exhibit electrochemical characteristics that differ from the behavior of the matrix (-Al), making these alloys susceptible to localized forms of corrosion.5,6,7,8,9,10,11,12,13 Birbilis and Buchheit5 reported interesting considerations about the electrochemical characteristics of intermetallic phases

Particular attention has been paid to intermetallic matrix composite particle-reinforced intermetallic compounds or ceramics. Materials Free Full-Text Manufacturing of Al2O3/Ni/Ti In this study, ceramicmetal composites in the Al2O3/Ti/Ni system were fabricated using the slip casting method. Two series of composites with 15 vol.% metal content and different solid phase contents were obtained and examined. A proper fabrication process allows obtaining composites enhanced by intermetallic phases. The microstructure of the base powders, slurries, and sintered composites

Microstructure and phase constitution near the interface

Apr 14, 2008 · Experimental results obtained showed that two kinds of intermetallic compounds (IMCs) are formed near the interface of copper and brazing seam region and those are Cu 3 Al 2 and CuAl 2 phases. Moreover, -Cu 15 Si 4 , AlSi and CuZn 2 are formed on Phase Equilibria of the Nb-V-Al Ternary System at 1100 and Jun 25, 2019 · In this study, two isothermal sections of the Nb-V-Al ternary system at 1100 and 1200 °C were experimentally investigated by means of back-scattered electron, electron probe microanalysis and x-ray diffraction. The determined isothermal sections at both 1100 and 1200 °C consist of five three-phase regions and ten two-phase regions, without any ternary compounds. The (Nb, V) phase forms Phase Selection in 6082 Al-Mg-Si Alloys, BHM Berg- und H Sep 01, 2012 · In this work two new kinds of particles in continuous casted 6082 alloy were observed. nm-size Al(Fe,Mn,Cr)Si particles and large U2-AlMgSi particles were found secondary to the expected, coarse Al(Fe,Mn,Cr)Si and Mg 2 Si on the grain boundaries and nm-size Mg 2 Si inside the grains. Because of the small size of the Al(Fe,Mn,Cr)Si precipitations an increase of the strength of the alloy

Plasma Sprayed NiAl Intermetallic Coating Produced with

Sep 01, 2011 · As indicated in Fig. 5, a less intermetallic phase was observed in the coatings after heat treating at 800 ⦠C, a fact which confirms the unexpected decrease in microhardness. The absence of intermetallic phases was perhaps caused by insufficient protection of the coatings against oxidation. 4. Properties of HDG coatingsand phases´ structure. The results are given on Figures 2 to 5 and in Table Blasting as a 4. surface pretreatment helps to create zinc coating with higher thickness, practically twice of original ones, but the appearance of coating is different. ing The morphology of zinc coat surface was measured by 3D microscope Keyence VHX-5000 (Figure 1). The Effect of Hot Treatment on Composition and Jul 08, 2019 · However, different distributions of the intermetallic phases and Fe-rich areas are usually observed after the evaluation of their structural characterization. Moreover, these areas are aluminum-depleted as a result of the thermal history of the particles in the flame.
